This is a big part of the discussion, I think, based on conversations with my conservative friends. They often complain about how they "can't say" certain words anymore. They'll make comments about how people are "too soft" these days. "Who feels pain from a word?" In your discord, they'd be the ones throwing around such words with reckless abandon.
I can sympathize, because I've yet to find a word that causes me pain by any stretch of the word "pain." There's no phrase, sentence, or utterance that has bothered me. I've been called all manner of racial epithets, gender epithets, and even sexual orientation epithets. I just can't bring myself to give a shit - nobody trying to hurt me is worth my time and so I ignore them / move on / mock them / laugh in their face.
I genuinely cannot put myself in the shoes of people who, for example, would feel a form of pain/offense at hearing the "n" word, for example. From my perspective, that would be just a great indication that whoever is using that word is not worth a millisecond of my time.
HOWEVER, I'm a straight white male that makes 140,000$/year and have no diseases whatsoever. So when my black friends tell me that certain words cause them pain, I believe them, because everyone's different.
I feel fear on rollercoasters to the point where I simply will not ride them. Some friends love rollercoasters. Objectively, I should not feel fear on rollercoasters. They are safer than hopping on my motorcycle for my 10 minute, 2 mile commute home. But, I do. So, I can take that experience and say "situations exist where I feel different emotions than other people do, for said situation." While I can't imagine what it feels like to hear a word and feel pain / offense, I can believe people when they tell me that a certain word makes them feel those negative emotions.
I'm not sure how to convince other friends that it's worth the effort to apply this baseline level of mutual respect. I wish I knew why I'm willing to respect others' feelings around words so I could share this learning. I guess, to me, it's logical? If someone wants to be referred to as male despite "appearing" female, don't throw a fucking hissy fit, just do it, who gives a shit? If people are saying "it's not cool to call people retards anymore," just... don't... do it... what are you actually losing? The ability to be an asshole to people in a certain specific way?
